Here’s the short version: don’t shoot steel-cased ammo (Wolf, Barnaul, TulAmmo, etc) in any gun you want to keep very long.

The problem isn’t really the steel cases, the problem is the weird alloy they use for the jacketed bullets. That stuff trashed a chrome-lined AR barrel in under 5,000 rounds, while the barrel shooting copper-jacketed ammo was still reasonably accurate after 10,000 rounds.

The exception comes for any rifle that can be rebarreled easily & affordably. Apparently, the steel-cased ammo is cheap enough that you can afford to buy a new barrel every 4,000 rounds and still save ammo compared to brass-cased, copper-jacketed ammo.

I don’t know what to do with my Mosin Nagant. I’ll probably continue firing cheap ammo. I’ve fired maybe 100 rounds total through it in the last few years.

About jurmond

'Jurmond' was the name of my first character in a homebrew D&D campaign. He was a gunslinger and tinker, creating and carrying strange weapons that belched fire and smoke. That was well over a decade ago but I still think of him whenever fiction and firearms collide, so it seems the perfect pen name for this project.
